MOBILE, Ala. — A Coast Guard official says a disabled cruise ship off the coast of Alabama is again moving toward the shore after a broken towline delayed the vessel’s slow journey back to port. Petty Officer William Colclough says a new tugboat has been secured and the Carnival Triumph is again making its way into Mobile. He says the ship will be further delayed because of the towline issue, though he did not give a new estimated arrival time. It had been expected to arrive Thursday night. An engine-room fire Sunday left the ship powerless. More than 4,000 people are on board the Triumph, and passengers face long bus rides or other travel hassles to get home once they arrive in Alabama.
